TV Affects dreams
We have dreams almost every night. Do you ever notice the colors of your dreams? Do you dream in black and white or do you dream in yellow, red and green?
New research suggests that the type of television you watched as a child has a great effect on the color of your dreams.
While almost all people under 25 dream in color, thousands of people over 55, all of whom were brought up with black and white TV sets, often dream in monochrome(黑白画面)。
“It suggests there could be a critical period in our childhood when watching films has a big impact on the way dreams are formed”, said Eva Murzyn, a psychology student at Dundee University in Britain who carried out the study.
Research from 1915 through the 1950s suggested that the vast majority of dreams are in black and white. But the tide(潮流) turned in the sixties, and later results suggested that up to 83 percent of dreams contain some color.
Since this period also marked the transition(过渡) between black-and-white film and TV and Technicolor(印染法彩色),an obvious explanation was that the media had been painting people’s dreams. However, there weren’t any firm conclusions.
But now Miss Murzyn believes she has proven the link. She made a survey of more than 60 people, half of whom were over 55 and half of whom were under 25.
She asked the volunteers to answer a questionnaire on the color of their dreams and their childhood exposure to film and TV.
She then analyzed her own data. Only 4.4 percent of the under-25s’ dreams were black and white. The over-55s who had had access to color TV and film during their childhood also reported a very low proportion of just 7.3 percent.
But the over-55s who only had access to black-and –white media reported dreaming in black and white about a quarter of the time.
Even though they would have spent only a few hours a day watching TV or films, their attention and emotion would have been heightened during this time, leaving a deeper imprint on their mind, Miss Murzyn told the New Scientist.
“The crucial time is between three and ten when we all begin to have the ability to dream”, she said.

Flickering lights are annoying but they may have an advantage. Visible light communication (VLC) uses rapid pluses of light to transmit information wirelessly. Now it may be ready to compete with conventional Wi-fi.
In a recent TED talk, Harald Hasas from the University of Edinburge,UK demonstrated one VLC prototype(原型),“Li-Fi", transmitting a video from a store-bought LED lamp to a solar cell to a laptop. “Li-Fi is essentially the same as Wi-Fi,except for a small difference- we use LED lights around us to transmit the data wirelessly as opposed to using radio," Haas says.
Once established, VLC could solve some major communication problems. In 2009, the US Federal Communications Commission(FCC) warned of spectrum (波谱)crisis: because our mobile devices are so data- hungry we will soon run out of radio-frequency bandwidth.Li-Fi could free up bandwidth, especially as much of the infrastructure is already in place."There are around14 billion light bulbs worldwide, they just need to replaced with LED ones that transmit data", says Haas.
The idea of transmitting data through the visible light spectrum is not new.Alexander Graham Bell transmitted sound via a beam of sunlight in 1880 using a photo phone, a sort of solar-powered wireless telephone. In the past several decades, a number of researchers have looked at using visible light to transmit data.
But what Haas seized on is the use of simple LED light bulbs for data transmission. LED bulbs are controlled by a driver, which can rapidly di the light or turn it on or off. Therefore, Haas figured, data could be encoded in subtle shifts of the light’s brightness. Eventually, he creaded a working transmitter and receiver system with an IKEA lamp and a solar panel.
Li-Fi stands to be much faster than Wi-Fi. According to Haas research, Li-Fi can achieve data density 1000 times greater than Wi-Fi,because Li-Fi signals are contained in a small area, as opposed to the more diffuse (分散的),radio signals.The system wouldn’t mean having to keep your lights on all the time either, Haas says---bulbs could be dimmed to such a point that they appear off, but still transmit data.
Now, Haas’ team hopes that Li-Fi could make its way into homes in a few years. The system can easily network any device with an LED light—an electric kettle, an oven. Eventually, this could bring about the Internet of Things era much faster. Haas also sees Li-Fi as a way to bring internet to remote location, using hilltop transmitters and rooftop solar panels. LED streetlights could even be used to form a network of outdoor Li-Fi, making it possible to stay connected when walking around the city.
But some sound a cautious note about VLC’s future. It becomes less powerful , for example,when light is blocked, wheather due to fog or other conditions.
1.By saying "There are around14 billion light bulbs worldwide”Haas intended to tell us that ______________
A. mobile devices will consume more data
B. radio-frequency bandwidth needs to be freed up.
C. VLC might solve the spectum crisis.
D. the world has a complete lighting infrastructure.
2.The underlined phrased “seized on“ in the passage is closet in meaning to “_____________”
A distinguished B. exploited C. created D. figured
3.We can learn from the passage that ________________________
A. Li-Fi can’t work outdoors.
B Li-Fi can work with LED lights off.
C. Li-Fi can be used with all household appliances.
D. Li-Fi needs improving to next diverse need.
